Abstract: A proppant includes a particle present in an amount of from 90 to 99.5 percent by weight and a polymeric coating disposed about the particle and present in an amount of from 0.5 to 10 percent by weight, based on the total weight of the proppant. The polymeric coating is formed from a curable composition comprising an isocyanate, an acrylate, and a polyol. A method of forming the proppant includes the steps of combining the isocyanate, the acrylate, and the polyol to form the curable composition, coating the particle with the curable composition, and curing the curable composition to form the polymeric coating.

Abstract: This disclosure provides a pigmented primer composition for forming an n-acyl urea coating on a substrate. The pigmented primer composition includes a polycarbodiimide-polyurethane hybrid. The pigmented primer composition also includes an acid functional polymer and an organic solvent, and includes less than or equal to 10 weight percent of water based on a total weight of the pigmented primer composition. The pigmented primer composition also includes a pigment, an inorganic filler, and less than about 100 parts by weight of toluene diisocyanate per one million parts by weight of the pigmented primer composition. The n-acyl urea coating exhibits corrosion resistance of 2 to 10 as determined using ASTM B117 and ASTM D-1654-08 on a substrate that is unpolished cold rolled steel, aluminum, or galvanized steel.

Abstract: A method of producing a polycarbodiimide polymer comprises heating a precursor compound at a desired temperature. The method further comprises combining the precursor compound, a diisocyanate compound, and a carbodiimidization catalyst to form a reaction mixture. Finally, the method comprises heating the reaction mixture for a first period of time at a first temperature, thereby reacting the precursor compound and the diisocyanate compound in the presence of the carbodiimidization catalyst to produce the polycarbodiimide polymer.
